Observation: Turnagain

Location: Sunburst, Tincan backdoor, Magnum

Route & General Observations

Three AAS groups went on the hunt for field observations on Magnum, Tincan and Sunburst. All reported pretty boring pits, which was great news for the snowpack but not so strong for the learning.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Gorgeous bluebird day with warm temps but a cool breeze that kept the snow quality gorgeous as well.

Snow surface

A tiny graupel layer topped a stout crust up to 1400' where it transitioned to graupel topped powder.


The most recent storm snow (30 cms) has 2 drizzle crusts within it that must have formed during the warmer days of that storm cycle and then the nights brought the cold snow sandwiched between. In all three locations, we were only able to find the 3/16 Buried Surface hoar below the second crust in one pit with no propagating results. In the others, it seemed like it had been absorbed into the stellars that it formed on. The compression tests were revealing that interface with moderate force, but no propagating results in any of the 21 holes we put in Turnagain Pass today.
